NET ENERGY AND PROTEIN UTILIZATION IN FISH BY INTRODUCING THE OBJECTIVE CRITERIA “CLARC OF ENERGY DISTRIBUTION“ AND „CLARC OF PROTEIN TRANSFORMATION“
AIM: To introduce the indicators Clarc of energy distribution (CED) and Clarc of protein/amino acid transformation (CPT) and adapt the methodology for their calculation in aquaculture. MATERIAL AND METHODS: A 50-day experiment was carried out with juvenile carp fish (C. carpio L.) reared in net cage...

| Summary: | AIM: To introduce the indicators Clarc of energy distribution (CED) and Clarc of protein/amino acid transformation (CPT) and adapt the methodology for their calculation in aquaculture. MATERIAL AND METHODS: A 50-day experiment was carried out with juvenile carp fish (C. carpio L.) reared in net cages. The following characteristics were reported: fodder (nutritional) coefficient, digestible energy, and crude protein intake per unit of weight gain, percentage of the boneless fillet, the chemical composition of the fillet. The methodology for calculating the respective Clarcs was described. RESULTS: The following values of the newly introduced indicators were established: Clarc of energy
distribution (CED) – 0.0866 (8.66%); Clarc of protein transformation (CPT) – 0.1052 (10.52%). |
